(AMZN) is being targeted by a group called No Music For ICE that is pushing for musicians to remove their music from the company’s digital catalog based on its ties with US Immigration and Customs Enforcement, or ICE.

“We, the artists behind No Music For ICE, are calling for our fellow musicians to cut ties with Amazon, until they end their contracts with ICE,” the group said in a statement on its Web site.

“Mass takedowns” will begin Friday and continue throughout Amazon’s holiday shopping season, the group said.

No Music For ICE sent an open letter to Amazon asking the company to terminate existing contracts with government agencies that commit human rights abuses, stop providing cloud services to organizations that power deportations, and end projects that encourage racial profiling and discrimination. The letter was signed by more than 1000 musicians.
